TRAILER TOWINGIn this section you will find safety tips and
information on limits to the type of towing you
can reasonably do with your vehicle. Before
towing a trailer, carefully review this information
to tow your load as efficiently and safely as
possible.
To maintain warranty coverage, follow the re-
quirements and recommendations in this
manual concerning vehicles used for trailer
towing.
Common Towing DefinitionsThe following trailer towing related definitions
will assist you in understanding the following
information.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers,
cargo and trailer tongue weight. The total load
must be limited so that you do not exceed the
GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-
ment (permanent or temporary) loaded in or on
the trailer in its loaded and ready for operation 
condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be sup-
ported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination. NOTE:
The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the ve-
hicle and have an accident.
Trailer Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. In most cases it should
not be more than 5% of the trailer load. You
must consider this as part of the load on your
vehicle.

Trailer Towing Weights (Maximum Trailer Weight Ratings)The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/Transmission Max. GTW (Gross Trailer Wt.) — withTrailer BrakeMax. GTW (Gross Trailer Wt.) —
without Trailer Brake Tongue Wt. (See Note)
3.6L Gasoline 5,000 lbs (2 268 kg) 1,653 lbs (750 kg) 249 lbs (113 kg)
5.7L Gasoline 7,716 lbs (3 500 kg) 1,653 lbs (750 kg) 386 lbs (175 kg) 3.0L Diesel 7,716 lbs (3 500 kg) 1,653 lbs (750 kg) 386 lbs (175 kg)
Maximum trailer towing speed is limited to 62 mph (100 km/h) unless local laws require a lower speed.
NOTE:
The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight
referenced on the Tire and Loading Information placard. Refer to “Tires – General Information” in “Starting and Operating” for further information.
Trailer And Trailer Tongue WeightAlways load a trailer with 60% of the weight in
the front of the trailer. Loads balanced over the
wheels, or heavier in the rear, can cause the
trailer to sway severelyside-to-side which will
cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the
cause of many trailer accidents. Never exceed
the maximum tongue weight stamped on your
trailer hitch. Consider the following items when computing
the weight on the front/rear axles of the vehicle:
•
The trailer tongue weight of the trailer.
• The weight of any other type of cargo or
equipment put in or on your vehicle.
• The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options, or au-

JACKING AND TIRE CHANGING
WARNING!
•Getting under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the jack
and fall on you. You could be crushed.
Never get any part of your body under a
vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service
center where it can be raised on a lift.
• The jack is designed to be used as a tool
for changing tires only. The jack should not
be used to lift the vehicle for service pur-
poses. The vehicle should be jacked on a
firm, level surface only. Avoid ice or slippery
areas.
Jack LocationThe scissor-type jack and tire changing tools
are located in rear cargo area, below the load
floor.
Spare Tire StowageThe spare tire is stowed under the load floor in
the rear cargo area.
Preparations for Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of
the vehicle closest to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel. 2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn the ignition OFF.
6. Block both the front
and rear of the wheel
diagonally opposite of
the jacking position. For
example, if changing
the right front tire, block
the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
7. For vehicle equipped with Quadra-Lift refer
to “Quadra-Lift — If Equipped” in “Starting and
Operating” for further information on disabling
automatic leveling.
